The 1jz comes with twin turbos
But it has a smaller displacement than the 7m, and u can get bigger power with a single turbo
Sum pplw with 1jz engine even does a single turbo conversion
The 1jz and the 7m are almost identical engines, but the 7m has better aftermarket support
The only downside is the hg problem
Besides that, the 7m is the superior engine to me
